WINDOW.

To all whom it may concern:

Be it known that I, AUGUs'rWoLFF, a citizen of the United States of America, residing in New York, in theborough of the Bronx, county and State of New York, have invented certain new and useful Improvements in Windows, of which the followlng is a specification. l

This invention relates to certain 1m' rovements in windows in which, instead o glass panes, a sheet or sheets of lwaterproof transparent and flexible material, such as celluloid are used, said sheets being adapted to be Wound up on suitable rollers in such a manner that the window can be partly 0r entirely opened so as to permit of partial or full ventilation, and in which the sheets are hel-d in tightly clamped and stretched posltion whether in partly or entirely closed position.

The invention relates further to means for clamping the sheets in closed or partly open positlon for use, and means for winding up or unwinding the sheets, according as the window is to be opened or closed.

In the accom anyin drawings, F1g ure l represents a 'ront-e evation of my 11nproved window, showing it in partlyopen position, Fig. 2 is a vertical transversesec- .tion of the same on line 2, 2, Fig. l, Fig. 3

` 1s a horizontal section, on line 3, 8, Fig. l,

drawn on a larger scale, and showing the mechanism for opening or closinfr the window, Fig. l is a detail side-elevatlon o-f the mechanism for raising or lowering the transparent sheet of the window, Fig. 5 is a perspective view of the means for tightly holding the transparent window-sheet in position, Fig. 6 is a vertical transverse sectlon of my improved window with an upper and lower window-sheet and the mechanism for moving the upper and lower half of the window-sheet separately from each other into a top and sill box, and Fig. 7 1s avertical transverse section of a window with a double sheet constructed on the same lines as the single-sheet window.

Similar letters of reference indicate corre-` sponding parts throughout the several views.

Referring to the drawings, a represents the window casing, al the upper or top boxes, and a2 the lower or sill box of my 1mproved window. The window, instead of being two sashes and glass panes, 1s made of one continuous sheet b of waterprooftransparent and perfectly clear cellulo1d, or

bands b3 are also Specification of Letters Patent. Patented N0V 22, 1910. Application filed September 15, 1909.

Serial No. 517,767.

1s guided at both sides in longitudinal slits of the jambs of the window-casing and extended into side-boxes a3. The opposite sideedges ofthe transparent sheet I) are provided with perforations b1 which are engaged by studs or projections b2 arranged on endless bands b3 that are stretched over driving and guiding rollers b5, b", located respectively in the sill and top box of the casing, as shown in Figs. l and 2. A second pair of endless bands b4 is arranged adjacent to the endless bands b3 and stretched over driving and guiding rollers Z1?, bs arranged adjacent to the rollers Zr", b, the bands b4 being provided with perforations registering with the studs or projections b2 of the endless driving bands b3, so that when the projections b2 enter the perforations of the window-sheet I) they enter also the perforations of the bands b4 and take the transparent window-sheet along for opening or closing the window-casing. On the shafts of the lower rollers b, b? are arranged gearwheels g, g1 which mesh with each other, said shafts being supported in bearings in the jambs of the window-casing and metallic supporting frames or keepers b9, while the shafts of the guide-rollers be, bs are likewise supported in bearings in the jambs and VAmetallic frames or keepers 61, as shown in Figs. .f3-.and 4:. The gear-wheels g of the placed in mesh with gearvwheels g2, which again engage gear-wheels g3 on the shaft of a winding-up roller g* to which the lower end of t-he window-sheet b is attached so as to be wound up on the roller or unwound from the same when the gearwhecls g are turned in one or the opposite direction. The shafts of the gear-wheels ,g3 and winding-up roller g4 turn in bearings 1n the side-walls ofthe sill-box and a suitable frame or keeper g5, as shown in Fig. 4l. The winding-up roller g4 is located in the sillbox a2 which is closed by a pivotedjnner sill d, and anouter stationary sill d1, tfhe latter beingv slightly inclined for shedding the rain-water. Between the adjacent adges of the inner-and outer sills the window-sheet I) is conducted when raising or lowering it by the action of the roller g4 and operating ba"nds.` Then the inner pivoted sill d is tilted, access is given to the gearing of the endless bands b3, b4 and the roller g4 in the sill-box. The window-sheet b is provided at its upper edge with an angular metallic equivalent material, of suiiicient size, which I strip e, which is attached thereto by rivets fforated edges of the sheet by the action of the gear-Wheels and windthe lowerpart of the sheet-on the winding-up roller. When v rection, then the sheet is unwound from the the angular strip e is raised, the train o f gear-wheels is operated in the opposite d1- roller, and the angular strip moved up against the top-part of the window-casing. In Figs. 1 and 2, the window is shown as partly open, but it can be entirely opened.

. by winding up' the sheet on the winding-up roller until the edge-strip abuts against the sill.

Alongside of the longitudinal slits in the jambs of the window-casing is arranged an outer stationary angular strip f, which is attached in fixed position to the jamb, and

e arrives at and an inner movable angular strip f1, which is locatedadjacent to the opposite-edge of the slits in the jambs, as shown in Fig. 3. The

kadjustable strip f1 is provided with horizontal slots f2 at its upper and lower ends and guided on headed pins f3 in the same. 'By means of a suitable lever ff, which is pivoted at its u per end to the'. movablel uide-strip f1 an attached by a pin f5 at s middle portion through a slot f6 .in the vmovable strip f1 with the jamb, the latter can be pressedrmly against the edge of the sheet so'as to hold it tightly in any desired position. The stationary stlrip f and the movable stripf1 are provided with grooves in their adjacent faces in which beaded strips f7, f8 are inserted so as to tightly clamp the sheet Z) and prevent any' ingress of Water to the side-boxes of the casing. The water running down on the outer surface of theiwindoW-sheet b is collected in the sill-box and conducted over the inclined bottom of the same to the outside. When it is desired to raise or lower the windowsheet, the movable strips f1 have to be released from the ed es of thesheet so that it canthen be freey adjusted. When the proper adjustment is made, the strips are tightly clamped to the window-sheet for holding it rigidly in position.'

In some cases, especially for windows of larger size, it is preferable to make the window-sheets in two sections, an'upper and a lower one, corresponding to the upper and lower sashes of the, ordinary window. This 1s shown in Figs. 5 and 6, A-In this case, the upper window-sheet bx is provided with an angular meeting strip e1 at its lower edge, 1n the same manner as the upper edge of the lower sheet. Two sets of raising and lower` ing mechanisms are then required, one being located in the sill-box and the other arranged in the top-box of the window-casing. Both sheets b andl b* are operated by the hand-rod, the hook-shaped end of which engages the angular strips e or e?. The clamping mechanisms for holding the upper'and loWer/window-sheets are of the same construction as the clamping mechanism for the single window-sheet shown in Figs. 1 to 4, while the guide-rollers for the endless operating bands are located adjacent to each other at the middle portion of the windowcasing.

For country houses and sections of the country having cold winters, double windoWs can be provided. Fig. 7 shows a double window with upper and lower windowsheets. In this case four adjusting mechanisms are required, two in the sill-box and two in the top-box. An air-space is formed between the window-sheets, while the clamping mechanisms for the edges of the sheets are constructed in the same manner. as in ,single-'sheet "windows,

The `advantages vof my improved window with waterproof celluloid sheets are that the objectionable breakage of the glass panes is avoided, that the windows can be o ened entirely so as to get the full venti ating eHect of the entire window-opening without any inwardly-projecting parts or wings, and

that no rain can enter into the rooms.

Whatever. rain or moisture is collected on` the outside of the window-panes is conducted into the sill-box and conducted olf to the outside.4 Owing to the firm clam ing of the edges of the sheets, they are he d firmly in stretched position so as to resist the strain caused by wind pressure, while the windows can be opened and closed in a vquick and easy manner and -clamped in partly lopen or closed osition.

Having thus descri ed my invention, I claim as new and desire to secure by Letters Patent:

l.
